Ezi ziqinisekiso zokuqala azinakuxoxiswana ngazo kwaye kufuneka zifakwe kwixesha lokuqala lokufumana, njengoko uvavanyo lwelabhoratri lomntu wesithathu lunokongeza iiveki ezi-3 ukuya kwezi-6 kumjikelo wokuthenga.

Ngaphaya kwemiyalelo yomthetho, iimfuno zesiteshi sokuthengisa zihlala zilawula umgangatho ophezulu wobungqina. Amaqonga amakhulu e-e-commerce, afana ne-Amazon, ngoku anyanzelisa imigaqo-nkqubo yokhuseleko kwizixhobo ezisebenzisa i-lithium-ion. Ukuzama ukudwelisa isibane se-USB ngaphandle kokungenisa iingxelo zovavanyo ze-UL 2054 okanye ze-IEC 62133 eziqinisekisiweyo ezivela kwilabhoratri evunyiweyo ye-ISO 17025 kudla ngokuphumela ekufakweni koluhlu olucinezelweyo. Amaqela okuthenga kufuneka adwelise iincwadana ezithile zokuthobela imithetho zabathengisi babo abajolise kubo ngaphambi kokuba bagqibezele iinkcukacha zemveliso nomthengisi waphesheya.

Xa utyalo-mali oluphezulu lwesatifikethi lufanelekile

Kukho iimeko ezahlukeneyo apho ukutyala imali kwiisatifikethi zokuzithandela, eziphezulu kuvelisa imbuyekezo enamandla kutyalo-mali. Ukulandela isatifikethi se-NRTL esipheleleyo (esifana nophawu lwe-UL okanye lwe-ETL) kwisibane sentloko esise-US kufuna inkcitho enkulu yokuqala—ngokuvamile ukongeza i-$3,000 ukuya kwi-$5,000 nge-SKU nganye kuvavanyo kunye neentlawulo zokudala iifayile, kunye neendleko zokuhlola eziqhubekayo zekota nganye. Nangona kunjalo, kwiimpawu zangaphandle zezinga leshishini, zoshishino, okanye eziphezulu, olu tyalo-mali ludla ngokuba lufanelekile.

Uphawu lwe-NRTL olwaziwayo luvula ngoko nangoko ukufikelela kwiindlela zokuthengisa eziphathekayo ze-Tier-1 ezigcina imigaqo-nkqubo yokunganyamezelani kwaphela kwizixhobo ze-elektroniki ezingaqinisekiswanga. Ngaphezu koko, amasebe okuthenga amashishini ngaphakathi kwamacandelo ezemigodi, ezokwakha, kunye neenkonzo afuna ngokungqongqo la manqaku ukuze kuthotyelwe ukhuseleko lomsebenzi. Ukongeza, ukuba neziqinisekiso zokhuseleko eziphezulu kunokunciphisa kakhulu iiprimiyamu zeinshurensi yoxanduva lwemveliso yenkampani—ezihlala zibangela ukuncipha kwe-15% ukuya kwi-20% kwiindleko zomgaqo-nkqubo wonyaka—ngaloo ndlela kunciphisa iindleko zovavanyo lokuqala kumjikelo wobomi bemveliso.

Imibuzo ebuzwa qho

Zeziphi izatifikethi ezifunekayo rhoqo kwizibane ze-USB ezithengiswa eYurophu?

Ubuncinane, jonga ukuthotyelwa kwemithetho enxulumene ne-CE, i-RoHS, i-REACH, kunye ne-WEEE, kunye nokuthotyelwa kwemithetho enxulumene nokupakishwa apho kufanelekileyo. Cela iSibhengezo sokuThotyelwa kwemithetho kunye neengxelo zovavanyo ezihambelanayo ngaphambi kokuba ufake ii-odolo.

Yintoni ekufuneka abathengi bayiqinisekise xa besebenzisa izibane ze-USB ezingena eMelika?

Qinisekisa uvavanyo lokhuseleko lombane olufanelekileyo, iimfuno ze-FCC zokuhambelana kwe-electromagnetic xa kufanelekile, kunye nokuthotyelwa kothutho lwebhetri. Cela iingxelo zangoku zelebhu ezinxulumene nemodeli echanekileyo kunye noqwalaselo lwebhetri.

Kutheni ukhuseleko lwebhetri luyinto ebalulekileyo yokuqinisekisa umgangatho kwizibane ze-USB?

Iiseli ze-lithium-ion ezinokutshajwa kwakhona zinokutshisa kakhulu, zidumbe, okanye zingaphumeleli ukuba iisekethe zokutshaja kunye nezokukhusela zibuthathaka. Qinisekisa ukhuseleko lokutshaja kakhulu, lokukhutshelwa ngaphandle, kunye nobushushu kwi-pack yebhetri kunye ne-PCBA.

Ngawaphi amaxwebhu ekufuneka amaqela okuthenga aqokelele kubaboneleli?
